$name = Utf8_decode ($name);

}

4. Open modules\projects\gantt.php

In about 214 rows

Comment and modify it as follows

/* IF ($locale _char_set== ' utf-8 ' && function_exists (' Utf8_decode ')) {$name = (Mb_strlen (Utf8_decode ($p [' Project_Name '])) > 25)? (Mb_substr (Utf8_decode ($p [' project_name ']), 0, 22). ' ... '): Utf8_decode ($p [' project_name ']); } else { *///while using charset different than UTF-8 we need not to use utf8_deocde $name = ((Mb_strlen ($p [' Projec T_name ']) > 25)? (Mb_substr ($p [' project_name '], 0, 22). ' ... '): $p [' project_name ']);  }
